Hi, I configured 1.4.3 with the following command: ./configure --prefix=/apps/ompii64R9 --with-sge --with-mpi-f90-size=large CC=/apps/intel/cce/9.1.039/bin/icc CXX=/apps/inte l/cce/9.1.039/bin/icpc F77=/apps/intel/fce/9.1.033/bin/ifort FC=/apps/intel/fce/9.1.033/bin/ifort --with-threads=posix --en able-mpi-threads --with-f90-max-array-dim=4 --enable-mpirun-prefix-by-default --disable-shared --enable-static --enable-cxx -exceptions
The important parts I believe are "--disable-shared --enable-static" . As you can see, the compilers were forced to use a release 9 intel compiler suite. The resulting mpixxx executables (after make;make install) have no intel library dependencies.

For my Open MPI installation, actually the executables such as mpirun and orted are dependent on those dynamic intel libraries, when I use ldd on mpirun, some dynamic libraries show up. I am trying to make these open mpi executables statically linked with these intel libraries, but it shows no progress even if I use "--with-gnu-ld" with specific static intel libraries set in LIBS when I configure open mpi 1.4.3 installation. It seems there are something for the compiling process of open mpi 1.4.3 that I do not have control, or I just missed something. I will try different things, and will report here once I have a confirmative conclusion. However, any hints or information on how to make open mpi executables statically linked to intel libs through intel compilers are very welcomed. Thanks! As for the issue that environment variables set in a script do not propagate to remote slave nodes, I use rsh connection for simplicity. If I set PATH and LD_LIBRARY_PATH in ~/.bashrc (which shared by all nodes, master or slave), my MPI application does work as expected, and this confirms Ralph's suggestions. The thing is that I just want to avoid set the environment variables in .bashrc or .porfile file, but instead, set them in the script, and want these environment variables propagating to other slave nodes when I do mpirun, as I could do for MPICH. I also try use the prefix path before mpirun when I do mpirun, as suggested by Jeff, it does not work either. Any hints to solve this issue?
